I can't think of a reason why anybody would use our address as sender address. Why not simple use a completly fake address or none at all?
Has it been a long time since you set up your own shipping-service account(s)? My immediate assumption was that they have become more security-conscious and make sure the account holder has a real, physical address which is printed on the label. If you're in the same town-- which your shipping service normally would be-- you know whether the 300 block of Union Street really exists or whether it would put you in the middle of the East River. It may even be coincidence that the address used is real as opposed to just possible.
For future reference, it might be useful to talk to the parcel service. If they really do have someone else's account linked to your address, they should be able to Do Something About It.
This is all assuming for the sake of discussion that

one of your minor employees isn't running a sideline in something they shouldn't.
And, yes, a bomb or equivalent went through my mind too. I kinda think I would have brought the parcel to the police without opening it.
